BaseTools: use double hyphens for CLANGPDB llvm-rc
When compiling rc files in environments where file paths begin with "/",
llvm-rc may incorrectly interpret absolute paths such as "/User/..."
as command-line options (e.g., "/U", "ser", "..."). This results in the
error "Exactly one input file must be specified". The issue was
initially observed on macOS, where user data is commonly located under
"/User" rather than "/home", but was later found to affect all platforms
where file paths start with "/". Using double hyphens ensures that all
arguments to the right are treated as positional arguments rather than
options. The use of double hyphens is supported by the LLVM command-line
argument parser and is safe in all such environments.

EmulatorPkg: use double hyphens for CLANGDWARF llvm-rc
Like BaseTools, CLANGDWARF uses llvm-rc to prepare resources. In
environments where file paths begin with "/", this can cause issues,
as paths to resource files may be interpreted as command-line options
rather than positional arguments. For example, "/usr/..." can be
interpreted as "/u", "sr", "...". To prevent this behavior, an explicit
separation of options and arguments using double hyphens has been
added.
